HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed March 23,1905. Serial No. 251,560. I

have invented certain new and useful Improvements in Hydrocarbon Burners, of which the following is a specification.

This invention relates to improvements in hydrocarbon-fluid burners, and especially to the type of such burners shown in my application for Letters Patent, Serial No. 236,77 6.

The especial objects of the improvements hereinafter described are to produce a burner that will more quickly and effectively generate gas and maintaina uniform heat from the combustion of such gas.

A further object is to simplify and cheapen the construction of the burner by avoiding the necessity for the use of quantities of asbestos or mineral-wool packing.

Other objects of general utility are attained through my invention, as will be readily seen by one skilled in the art.

In the accompanying drawings,which form a part of this application, Figure l is a view, partly in elevation and partly in section, of a burner constructed according to my inven' tion. Fig. 2 is a top plan view of the device with parts removed. Fig. 3 is an elevation, on an enlarged scale, of the reservoir, which forms a feature of the device. Fig. 4 is a vertical section through the reservoir. Fig. 5 is a top plan View of one of the fluid-distributing pipes, and Fig. 6 is a top plan View of another fluid-distributing pipe.

Referring to the details of the drawings, A represents a portion of a hydrocarbon-fluidholding tank, from which the fluid is supplied by gravity to my improved burner through a pipe a, connected with the bottom of the tank by a stop-cock o The pipe 64 leads to and is connected with a Y coupling, the branches of which are respectively connected with hand-operated valves of a of well-known form. These valves are respectively connected with short lengths of pipe (0 0 which are screwed into suitably-threaded openings 6 b in the reservoir B. Preferably these.

pipes are packed with a filtering non-combustible material, as shown in Fig. 2.

The reservoir B is of cast-iron in the form shown and has its interior divided into two chambers by a vertical partition 6 (Shown in dotted lines in Fig. 3.) Communicating with the respective chambers are inlet-openings I) or 6 with which the pipes a (0 respectively,

connect, and outlet-openings 72 with which the distributing-pipes D and E, respectively, communicate. In the top and bottom of the reservoir are screw-plugs b fitting suitable openings, through which the packing G for said reservoir can be inserted and removed. At the bottom of the reservoir a foot 6* is formed, in which an open slot 6 is provided to receive a bolt 5 by which the reservoir is connected with an extension 0 of the drip tray or pan 0, which is arranged below the burner elements to be described. The pan C is also formed with slotted lugs c on opposite sides and with transverse ribs 0 as clearly shown in Fig. 2. The transverse ribs 0 support the distributing-pipe D, one end of which has a threaded engagement with one of the openings 6 in the reservoir B. This pipe is bent to form a single coil, as shown in Fig. 2, or a double coil, as shown in Fig. 5, and has its outer end bent upwardly, forming a vertical pipe d, on the end of which is screwed a T-coupling 0Z with which are connected horizontal pipe-sections 0Z d which are closed,. respectively, by a cap d and a screw-plug 0Z Depending from the pipes d are perforated teats d, which form jets, through which the fluid is projected downwardly in the form of sprays, as shown in Fig. 1.

The distributingpipe E is connected at one end with the other threaded opening 6 extends over a portion of the pipe D, and ternates in a coil a in the end of which is inserted a teat a, from which the fluid escapes in the form of an upwardly-directed spray. A T-coupling e is arranged about midway the pipe E and has connected therewith a short horizontal pipe c, with which is connected an elbow 3 which connects with a pipe 6 the outer portion of which terminates in a coil 6*, in the end of which is inserted a teat 6 from which the fluid escapes, as in the corresponding teat e.

Arranged over the pipes D and E is a dome F, which is formed with an open bottom and with openings f f in its top, which are arranged directly over the coils 6* 6 The dome is secured to the pan 0 by suitable bolts, which pass through ears f formed on opposite sides of the dome and at its lower edges, and through the ears 0 on the pan. The lower edge of the dome is spaced above the pan a suflicient distance to permit air to enter freely at its base and circulate around the coilse c and pass out through the openings f.

In practice a burner constructed and arranged as above described will operate as follows: The valves in the cocks a and a will be opened, thus permitting fluid to pass through the pipe into one chamber of the reservoir B and therefrom through the pipes D, d, and d to the jets (Z d, at which points the fluid will be ignited by the operator. The resulting flame will be projected against the coils 0 6 thus heating the latter sufliciently to generate gas as soon as fluid is admitted thereto from the pipe a and reservoir B by opening the valve in (4*.

It will be understood that the relatively large heating area of the coils e 6 resulting from their shape,will facilitate the quick heating of same and the easy maintenance of a gasgenerating temperature with a relatively small consumption of fluid. In practice some fluid will flow from the jets (Z upon the coils and cover the latter, and this will ignite as soon as a lighted match is applied to the jets, thus surrounding the coils with a Zone of flame calculated to heat them in a very short time.

It will be understood that after gas is generated at the coils the valve in cock (5 will be closed, thus cutting off the flow of fluid from the pipe 61 and thereafter the constant supply of fluid will flow through the valve a, pipe at, &c.

coils and cooperating parts, it is evident the number may be increased to provide additional heating capacity in the burner.

WVhile I have shown but two coils, means for conveying fluid to said distributing-pipes, said means being controlled independently of the coil fluid-supply means.

2. In a hydrocarbon-burner, a dome having combustion-chambers therein and provided with an open bottom and with openings in its top, gas-generating coils arranged in said chambers and having apertures therein arranged below the openings in said dome, means for conducting fluid to said coils from a suitable supply-tank, fluid-distributing pipes adapted to project fluid upon said coils, and means for conveying fluid to said distributing-pipes, said conveying and conducting means comprising a storage-reservoir and independently-controlled pipes.

In testimony whereof I aflix my signature in presence of two witnesses.
